HAIR-WAVING DEVCE.

kApplication filed September 22, 1922. Serial No. 589,746.

This invention relates generally to devices for waving hair.

In companion application Serial No. 589,- 745, led September 22, 1922, adevice of this general nature is described in which there is included astrand-heating tube having improved means for closing the end of thetube adjacent the head of the person whose hairV is being treated. Meansfor heating the tube occupied an enclosing relation to `an intermediateportion of the tube V and adapter tubes were arranged to be inlsieserted in the heater tube to cause the enclosing tubes to closely iitthe external dimensions of the strand and reduce the amount of air Spacesurrounding the coiled strand to a minimum.

In the present invention provision is made for the use of a standardsize heaterin connection with which is used a heater tube correspondingin size to the strand to be treated rather than to the size of the boreof the heater. Special means are provided for holding the heater tube inplace in the bore of the heater with the tube in contact with one sideof the bore of the heater. The invention also includes closure means forthe end of the tube which may be readily opened to facilitate thecooling and drying of the treated strands while still in place in thetube.

Other features of the invention will be hereinafter referred to.

In the drawings, in which a preferred embodiment of the invention hasbeen selected for illustration,

Figure 1 is a view in longitudinal section of a device embodying a partof the invention. l

Figure 2 is a view in side elevation of a heater tube forming part ofthe device.

Figure 3 is a longitudinal sectional view of an end portion of a heatertube provided with a modified form of closure.

Figure 4. ris a view in side elevation of the device shown in Figure 3.

Figure 5 vis a view similar to Figure 3 showing the closure in openposition.

Figure 6 is a sectional view on the line 6-6 of Figure 5.

Figure 7 is an enlarged sectional view taken on the line 7-7 of Figure1.

Referring to the drawings for a more detailed description of theinvention, Figure Vl shows an electrical heater 5 provided with alongitudinal bore 6 in which to receive tubular elements such asis shownat 7 in which a coiled strand of hair as at 8 is inserted for thedesired heat treatment.

A feature of the invention resides in the provision of a spring frictionmember 9 on cach heater tube, by the use ofwhich heater tubes ofdifferent sizes and relatively smaller diameter than the bore of theheater may be frictionally held in place within the heating device. Bythis construction'l am enabled to make use of heater tubes-havingsubstantially the same internal diameter as the outside diameter of thecoiled strand undergoing treatment and to employ such Vvarious sizedtubes with heaters having bores of a single standard diameter.

fn order to apply the heat developed by the heater device 5 to theheater tube in the most effective manner, the spring holding member 9 ismounted along one side of the tube in such a way as to hold the oppositeside wall of the heater tube in direct contact with the inner surface ofthe heater. This arrangement reduces to a minimum the heat insulatingeffects of the air gap that must necessarily exist between the heaterand a container tube of smaller diameter than the heater bore, in thatdirect conduction of the heatis had between the contacting portions ofthe contiguous surfaces of the engaged parts.

In order to close the end of the heater tube adjacent the scalp of thecustomer a closure device l0 is made use of which includes two gatemembers l1 and 12 having interengaging movement toward and from eachother across the end of the tube. A. pair of spring arms lreinovablycarried by the tube normally presses the closure gate members towardeach other into closing relation to the end of the tube and clampingrelation to the strand of hair 8 enclosed in the heater tube. A heatinsulating band or terminal member 15 formed of felt or the likeprevents the transfer of heat from the heater tube tothe gate memberssuch as would cause discomfort to the customer.

In order Ato facilitate and hasten the cooling of the treated strandfollowing the heating operation, a removable closure, or one that can beopened to give access between the interior of the heater tube and theatmosphere, is provided for the outer end of Vif desired to define alongitudinally restricted chamber section for strand.

e In Figures 3, 4, and-6 of the drawing a closure member is slioivnhaving the nature of arvalve and adapted to be opened or closed toprovide communication 'between the inthe coiled terior of the heatertube 7 and tlie'atmosvec .during the heating operation.

phere or to shut off such communication The closure member consists of acup-shaped member :2O

Vhaving ports 21 in its side Walls adapted to be inoved into and out ofregistrationA With iorts 22 in the Wall of the heater tube. referablythe valve or closure member 2O is movable axially or longitudinally ofthe heater tube and so arranged that a slight push inward will open theports so that a minimum of manipulation of the heated tube isrequired toeffect the opening of the ports at the end of the strand heatingoperation.

In the form of the invention Ashowny in Figures 1 and 2 heat insulatingmaterial 2a `may be provided on the heater tube to permit of thehandling ofthe tube While the cork is being removed. An insulated handleportion 25 is also provided on the heater device 5 to facilitatemanipulation of the device. lt Will be seen that following the4operation yof heating the coiled strand which has been moistened With asuitable hair softening material., the outer end of the heater tube maybe opened either by removal of the plug member 16 or by opening theclosure valve 2() to aid in the cooling of the heater tube and itscontents. lt Will be clear that the heaterdevice 5 may at the same timebe removed leaving the heater tube exposed on allv sides 'to atmospherein addition to leaving the outer end open to the air. Y My presentimprovements are particularly adapted for the process of permanentWaving of natural hair on the human head, and they serve to materiallyshorten the time heretofore required in this Work and also to greatlylessen the discomfcrts Which the subject has heretofore necessarily beenrequired to undergo. My improvements also mini- Vmize'the chances ofinjury or impairing the hair structure, Which impairment is likely ofheat-conducting material and having a less diameter than the diameter ofthe bore Of the heater device, and spring means Cal* ried by the tubularmember and adapted to engage the inner 'surface of the bore to hold thetubular member in place therein.
